An Arduino by any other name…

April 27, 2015 | Arduino | By: Mark VandeWettering

I was trying to make some headway on my robotic platform project, so I went digging through boxes in my office to find the large, 12v SLA battery that I know I have somewhere. While searching I found a bunch of stuff: hundreds of red LEDs in a pack, two Arduinos, a Sparkfun breakoutboard for […]

Using a SainSmart LCD panel with the Arduino 1.6.3 IDE…

April 22, 2015 | Arduino, My Projects | By: Mark VandeWettering

Yesterday I experienced some frustration with the SainSmart I2C LCD Module that I bought to help Pete and Bill uncover the problems that they’ve been having. If you go and read, you’ll find that I had a lot of difficulty finding the right combination of code that can be used with this module. Eventually, I […]

A (not entirely simple) LCD display for the Arduino…

April 21, 2015 | Amateur Radio, Arduino, My Projects | By: Mark VandeWettering

I am a big fan of Bill Meara N2CQR and Pete Juliano N6QW, hosts of the really great Soldersmoke Podcast. Together, they chat about homebrewing ham radio equipment, and what they’ve learned in their lessons along the way. Their “tribal knowledge” is of terrific help to someone like me who keeps making small forays into […]

New I2C peripheral: 6 DOF IMU, $5.89

April 20, 2015 | Arduino, My Projects | By: Mark VandeWettering

This little gadget arrived via Amazon Prime today: a three axis gyroscope/accelerometer that can be programmed via the I2C bus. I didn’t really have any reason to get one, other than simple curiosity, although I suspect that possibly mounting one on my (as yet unfinished) robot platform might be able to determine motion parameters of […]

Tinkering with individually addressable LEDs…

April 19, 2015 | Arduino, LED, Microcontrollers, My Projects | By: Mark VandeWettering

While digging around looking for an LCD module I thought I had stashed somewhere, I encountered a bag with some of 8mm individually addressable RGB LEDs that I had never done anything with. For fun, I thought I’d wire a few of them up on my breadboard and see if I could get them to […]

More ESP8266 Experimentation: Giving it the Boot…

April 4, 2015 | Arduino, Hacking, LED, My Projects | By: Mark VandeWettering

Got a chance to play around a bit more with the ESP8266 tonight. I dug out a nice little dual output power supply board that I had got from tautic.com with the hope that it would eliminate some of the erratic behavior that I had observed before. Sadly, that didn’t seem to solve my problem. […]

Not all is easy-peasy with the ESP8266, with a short addendum

April 3, 2015 | Arduino, Development Boards, Embedded | By: Mark VandeWettering

Okay, after I did my quick video record yesterday re: the ESP8266, I continued to play with it a bit more. And, it must be said, I had a little bit of difficulty which I thought I would write up so that other people who are experiencing the same issues might be able to comment, […]

First electrons for the ESP8266…

April 2, 2015 | Arduino, Development Boards, Embedded, Internet of Things, My Projects | By: Mark VandeWettering

In the telescope making world, we call the first time that a telescope is used to look at the sky “first light”. I’ve decided to call the first time I load some code onto a new development board “first electrons”. A few weeks ago, when I did a video that illustrated some of the bucket […]

More on Arduino v. Arduino…

April 2, 2015 | Arduino | By: Mark VandeWettering

Make just published this interview with Arduino founder Massimo Banzi about the internal schism that’s currently embroiling the Arduino community. It is true that this represents only one side of the story, but it does seem that at a minimum, Arduino SRL (represented at http://arduino.org) has copied much of the Arduino LLC website without credit […]

Arduino? Perhaps we need OurDuino…

March 31, 2015 | Arduino | By: Mark VandeWettering

It’s no secret that I’ve been a fan of the Arduino. More than any other board, it’s got me into hacking little bits of hardware and programming in the small, and has been part of numerous projects that I’ve tinkered together, and others that I’ve helped mentor young people with. It’s a cute platform for […]

Minor tweaks to Arduino Morse Sketch…

March 30, 2015 | Amateur Radio, Arduino, My Projects | By: Mark VandeWettering

Commenter Andy wanted a version of my classic code that could generate a tone instead of just blinking an LED. I mentioned that I had done this before, but frankly couldn’t find the source code, so I modified my existing program to implement the simplest possible tone: a simple square wave. Rather than using a […]

Tiny BASIC on a Tiny Display…

March 25, 2015 | Arduino, My Projects | By: Mark VandeWettering

Early in 2012, I posted a small version of Tiny BASIC that I had adapted to run on the Arduino. It is based upon code which was written by Mike Field, and based upon an earlier version of TinyBasic for the 68000 written by Gordon Brandly, which owes its roots to Palo Alto Tiny BASIC, […]

Using the Parallax PING))) ultrasonic distance sensor

March 24, 2015 | Arduino, My Projects | By: Mark VandeWettering

I intended to play around with some of the NRF24L01 radio modules I have around, but my brain didn’t feel up to it after a day of debugging. So, instead i dusted off a Parallax PING))) sensor that I’ve had around for a long time. I thought it might be fun to see if I […]

My version of minilife2 for the Arduino…

March 24, 2015 | Arduino, My Projects | By: Mark VandeWettering

Without a lot more explanation, I did a bit more work on my implementation of Conway’s life, reducing the overhead so I can implement the full 128×64 bit resolution of the OLED display. I also hardcoded an initial pattern: the classic Gosper glider gun. It runs at about 1.625 frames/second, so a new glider is […]

A few more notes on my implementation of Conway’s Life…

March 23, 2015 | Arduino, My Projects | By: Mark VandeWettering

I received a couple of email and twitter queries about various aspects of the code, so I thought I would add a followup to yesterday’s post. First of all, I received a query as to whether it was “open source”. Frankly, the code is so minimal and so obvious I didn’t even consider it worthy […]
